Method for manufacturing electroluminescent device

A method of manufacturing a light-emitting device, comprising:

• providing a substrate including a first pixel, a second pixel and a third pixel configured to emit different colors;
• forming a first light-emitting layer over the substrate through a first shadow mask to cover the first pixel and at least a portion of the third pixel;
• forming a second light-emitting layer over the substrate through a second shadow mask to cover the second pixel and at least a portion of the third pixel;
• forming a photosensitive layer over the substrate, wherein the photosensitive layer covers a portion of the first light-emitting layer that is over the first pixel and a portion of the second light-emitting layer that is over the second pixel, and the photosensitive layer exposes portions of the first light-emitting layer and the second light-emitting layer that are over the third pixel;
• removing the portions of the first light-emitting layer and the second light-emitting layer that are exposed through the photosensitive layer;
• forming a third light-emitting layer over the photosensitive layer and over the third pixel;
• and
• removing the photosensitive layer simultaneously with a portion of the third light-emitting layer that is over the photosensitive layer.

A method of manufacturing a display panel, comprising:

• forming a first light-emitting layer over a substrate through a shadow mask, wherein the substrate includes a first pixel, a second pixel and a third pixel;
• removing a portion of the first light-emitting layer that is over the second pixel and is exposed through a first photosensitive layer;
• forming a second light-emitting layer over the first photosensitive layer and over the second pixel, and removing the first photosensitive layer simultaneously with a portion of the second light-emitting layer that is over the first photosensitive layer;
• removing a portion of the first light-emitting layer that is over the third pixel and is exposed through a second photosensitive layer;
• and
• forming a third light-emitting layer over the second photosensitive layer and over the third pixel, and removing the second photosensitive layer simultaneously with a portion of the third light-emitting layer that is over the second photosensitive layer.
